The real estate firm MDA DataQuick has released new numbers for the housing market, and it’s more of the same. The median value for a Bay Area home is now $330,000, down from its peak at $665,000 in the summer of 2007. And foreclosures accounted for roughly half of all sales in December. The Chron profiles one man who bought an Oakland rental triplex for $106,000; the property was once worth $557,600. Times have changed.
